Novell have a product called PlateSpin PowerConvert that will do P2P, P2V and V2P reliably across a very wide range of platforms and operating systems. It's not cheap (list price is $200 per conversion) but it will do both hot (live, minimal downtime) and cold migrations.

You can prepare all of your migrations in advance, scanning both the source and target systems, defining the parameters for the migration and it will give you a very comprehensive analysis highlighting any issues that need to be resolved before you start.

I used Acronis True Image Workstation with the Universal Restore addon to do this, quite a lot, around 2006 onwards. It worked very well, although I have not used it for some time. I did use it again more recently, when I started getting into virtualisation, around three years ago.
